Answer:
D
Step-by-step explanation:
X represents the number of lawns Jimmy cuts so the function would be 5x, meaning that for each lawn he cuts he earns $5. The $25 would be the flat rate that he earns just by going to wotk.
f(x) = 25 + 5x
x is the number of lawns
f(x) is the money he earn
25 is a constant amount
So we can say that for each lawn he cut he earn $5 more, and just by cutting he already earn $25 so the right awnser is D.
b
Answer: 1/3 =0.33
just substitute the values of x and y into the expression to get
4(2)+1 /3(3)^2
=8+1 /3×9
=9/27
=1/3
=0.33
4.5 gallons
x=16/t
t=4 so
16/4 = 4
4 is your answer.
